Nope, not here, not yet at least.
Stop. Look at your dogs (plural, because you need two for this). Are they lying in unison, parallel? Are they mirror images, or as they were today, yin and yang, curled in semi-fetal positions mimicking the timeworn zen drawing, one black (Manny) and one white (Buddy).
Biologists have a term – “allelomimetic behavior’ – that describes animals doing the same thing at the same time. A flock of birds, jinking left simultaneously. A school of fish, describing abstract forms as one in tropical waters. Dogs, too. If you have two, or run with a bunch for fun or profit, maybe you’ve seen it. Matching pace, maneuvering as if linked by iron rods.
But while holding still, or sleeping? What mysterious vibe bridges the five feet between Manny and Buddy, putting both left rear feet under, while right face touches the ground and left front foot is outstretched? They could be posed by a photographer, or Photoshopped, but it’s real, and unrehearsed.
Is it a deep-seated genetic trait? Are they watching for prey, or predators? A rival pack? Is it simply allelimometic behavior frozen in time as they lie down for a snooze?
I’m intrigued, and it makes some great photos. If I only had a camera when they did it.

i have seen strings of dogs do this while other strings do not, my dogs do not do this, i think its a genetic trace as the dogs i have seen do this are usually related.
That’s interesting! We have had related Corgis that do a little upside-down dance, so your theory makes a lot of sense.
